Crusher

Abstract

The invention discloses a crusher. The crusher comprises a charging device, a discharging device, a feeding device and a crushing device; the feeding device consists of feeding rollers and a material poking roller; the crushing device consists of a rotor, a fixed cutter and a filter screen; the circumference of the rotor is provided with fly-cutter seats; the included angles between the adjacent fly-cutter seats are equal on the circumference; fly-cutters are fastened on the fly-cutter seats through bolts; gaps are reserved between blades of the fly cutters and the fixed cutter; the fixed cuter is fastened on a fixed cutter beam by a bolt through a pressing plate; the fixed cutter beam is connected with the feeding rollers through a feeding transition plate; and the feeding rollers are parallel to each other, and the rotation directions of the feeding rollers are consistent with each other; and the material poking roller is fixed on a material fixing roller cover in which a hinge is taken as a rotation center. The crusher is high in crushing efficiency, low in energy consumption, and good in effect of crushing wood, core wood, cotton straw and other biomass, is suitable for crushing municipal solid waste and industrial refuse simultaneously and runs stably.

Description

technical field [0001] The invention relates to the fields of biomass energy development and garbage power generation, in particular to a shredder for biomass fuel and garbage. Background technique [0002] In my country's biomass power generation technology and waste power generation technology, the crushing of fuel is a technical problem. Biomass fuels in my country are generally crushed by German drum crushers. The advantages of crushing are low energy consumption. The disadvantages are poor crushing stability, high equipment maintenance costs, high quality requirements for biomass fuels, and stones or tree stumps mixed in the fuel. It will cause a large impact on the rotor and damage the shaft and bearing of the rotor. Domestic hammer crushers are generally used for garbage crushing. The advantage is that it has a good crushing effect on hard garbage fuels. The disadvantages are high energy consumption, low production capacity, large equipment maintenance, and limited ty...

Problems solved by technology

Biomass fuels in my country are generally crushed by German drum crushers, which have the advantages of low energy consumption for crushing, but the disadvantages are poor crushing stability, high equipment maintenance costs, high quality requirements for biomass fuels, and stones or tree stumps mixed in the fuel. Cause a large impact on the rotor, damage the shaft and bearing of the rotor

Domestic hammer crushers are generally used for garbage crushing. The advantage is that it has a good crushing effect on hard garbage fuel. The disadvantages are high energy consumption, low production capacity, large equipment maintenance, and limited types of crushed garbage.
